We need to unlock our Android devices for various reasons. The first reason is the presence of freedom. Once your phone is unlocked, you gain the freedom to use it on many carriers. You are not limited to using a particular carrier. Secondly, we unlock android phones for travelling purposes. If you are travelling abroad, your first carrier is likely to charge you sky-high roaming fees for you to use your device while you are away. Unlocking your phone, therefore, opens the door for affordable wireless services while you are away. Once your phone is unlocked, you have access to Roam Mobility, and with Roam Mobility, the charges are reduced. For instance, the Canadian travellers can enjoy texting, talking and data in the Mexico and the USA for a 95% reduction in charges on most major carrier charges.

The unlocking procedure may require security exploits.

Once you root the device, you can replace pre-installed apps, and restore system files. Root also allows phone users to backup their files and devices. Just like unlocking, rooting may require security exploits in some phones.
